I believe that post was making the assumption that you switched to
systemd. If you do not wish to switch to systemd yet, then no action
is required. See [0] for some details.

In order to use systemd (after the upgrade), either append
init=/bin/systemd to your kernel commandline or install
systemd-sysvcompat (which will conflict with sysvinit). If you do not,
then you'll stay with initscripts.

No, partial upgrades will not work well (as always). Though, as I
mentioned, saying "yes" does not really mean anything unless you
actively switch on systemd.
